Arcom Embedded Linux Technical Manual Developing software for AEL

Developing software for AEL

To ensure that an application is able to run correctly when installed on a target board,

you must ensure that it is compiled and linked against the libraries that are present on

the target system. This is particularly true when the processor architecture of the target

board differs from the processor architecture of the host system, but is also true if the

processor architecture is the same. The act of compiling for a target system that differs

from the host system is known as cross compilation.

The AEL host environment contains a suite of cross compilers and other tools, as well

as the libraries and headers that are necessary to compile applications for use on AEL.

It also contains various tools that are useful when working with AEL target systems.

Host system requirements

The AEL host environment requires a host Linux distribution that is compatible with the

Linux Standard Base

(LSB) version 1.3. The LSB is an attempt by Linux distribution

vendors to specify a set of basic functionality that is present on any Linux distribution.

Each Linux distribution vendor who supports the LSB provides a package which

ensures that the LSB functionality is present on the system. Many Linux distributions do

not include LSB support in the base installation, so you may need to add it.

The LSB support package is by its nature tightly coupled with the Linux

distribution and version. It is therefore important that you install the LSB

package for the exact distribution version you are using as supplied by the

distribution vendor.

n LSB support package downloaded from anywhere else is

unlikely to function correctly.
